Write a NumPy program to combine a one and a two dimensional array together and display their elements

import numpy as np
x = np.arange(4)
print("One dimensional array:")
print(x)
y = np.arange(8).reshape(2,4)
print("Two dimensional array:")
print(y)
for a, b in np.nditer([x,y]):
    print("%d:%d" % (a,b),)

Sample Output:

One dimensional array:                                                 
[0 1 2 3]                                                              
Two dimensional array:                                                 
[[0 1 2 3]                                                             
 [4 5 6 7]]
